Benfica head to West London trailing 1-0 on aggregate after Salomon Kalou's goal in Portugal earned Chelsea a potentially key away first leg victory.

Cardozo, though, has not given up hope of his team turning things around, and the forward has called on his team-mates to give their all against their Premier League counterparts.

"Perhaps the tie is 60-40 in Chelsea's favour now, but that does not mean it is lost," the Paraguay international said.

"It is perfectly possible to overcome a goal [deficit] in Europe. Chelsea's strikeforce is very good. Just mentioning their names proves that, but it is not always enough to win games.

"Benfica want an open and crazy game, not a tactical one. That would suit the English, [who will look] to manage the situation with their goal advantage.

"The match is going to be very tough. We know that and we are prepared, but we are going there with the sole aim of scoring goals and winning. That way, we can obtain passage to the semi-finals, which is our great dream.

"We deserved more in Lisbon, but football has those things and justice is not always shared out fairly on the pitch. Now we have to take advantage of these 90 minutes or more to keep on making history in the Champions League."

On a personal level, Cardozo is eager to perform to his maximum, telling Goal.com: "At Stamford Bridge we, the Benfica strikers, will need to be the protagonists because we need to score goals.

"I am up for that challenge and I want to play my best game of the season."
